2ppm (peak-to-peak). Each output can source and sink
10mA and has an independent sense line. This product
has a temperature drift of 6ppm/°C (max) over the ambi-
ent temperature range of -40°C to +125°C and an initial
accuracy of 0.04%. Three pairs of output voltages are
available: 5V/2.5V, 4.096V/2.048V, and 2.5V/1.25V. The
product operates with an input voltage range of 2.8V to
5.5V and has sufficient headroom for the highest voltage.
It consumes a mere 150µA (typ) of quiescent supply cur-
rent per reference. The dual voltage outputs make this
device ideal for precision ADC applications where the
